Abstract: To prevent coupling breakage between an elastic body and an outer ring due to friction heat of an armature and a rotor, an solenoid clutch coupling is provided with an elastic body (3) elastically coupling a hub (10) attached to a rotation shaft (6), and an outer ring (20) coupled to an armature (5) solenoidally moved close to and apart from a rotor (4), a sleeve (40) buried in an outer peripheral portion of the elastic body (30), a fit layer (32) constituted by a part of the elastic body (30) in an outer peripheral side of the sleeve (40) and attached to an inner peripheral surface of the outer ring (20), and non-cylindrical surfaces (21a) engaging with the fit layer (32) in a circumferential direction, and axial stoppers (23, 24) to an outer periphery of the elastic body (30) in a sleeve (21) of the outer ring (20).
